Security

Data or IT security.

The challenge for security is that - unlike functional safety - , security mechanisms need to adapt continually to new threats and gaps in security can ultimately impair production with all its functional elements.

The demands that the spheres of IT and automation place on security vary considerably. While the confidentiality of information is the number one priority in an office environment, the availability of data is most important in the production area, as this is a key requirement for a smooth manufacturing process. An international standard (IEC 62443) Is currently being draftedwhich is intended to harmonise both worlds.

As the threats from the cyberworld are dynamic, safety and security will remain two separate issues in future, although they will be closely linked.
